Experimental Study on the Fire Whirl Characteristics of Oriental Oak Leaves

굴참나무 낙엽의 Fire Whirl 특성에 관한 실험연구

  • Published : 2009.08.30

Abstract

The fire whirl occurring in the urban and/or wildland fire is generated by the instabilities of atmosphere. The fire whirl is a rare phenomenon, but highly destructive because it has high inhalation and lift force. In this study, experimental study is performed with oriental oak leaves, for investigating of the fire whirl characteristics occurred in wildland fire. As a result of experiment, the circulation intensity increases as increasing of the induced air velocity, and then the fire whirl occurs. Also, the heat release rate and flame height increase 22% and 18% in highest circulation.

Keywords
